Fire-weary residents at Sarabah in Queensland's Scenic Rim have had a reprieve with authorities downgrading the bushfire warning level in the area, but conditions are expected to worsen on Saturday for the state's southern region.

Key points:

More than 50 fires are burning across Queensland but none pose an immediate threat

Firefighters are most concerned about the Scenic Rim blazes with the Sarabah fire expected to burn for days

Fire conditions are expected to worsen on Saturday, as a dry wind sweeps across parts of southern Queensland

Queensland Fire and Emergency Services (QFES) said at 5:30pm that its warning for the area had changed to "stay informed", with the blaze travelling in a north-westerly direction from Pyramid Creek in Lamington National Park towards Lamington National Park Road at Sarabah.

It said fire crews would continue to work in the area to contain the fire and that people in the area would be affected by smoke, which would reduce visibility and air quality.

There is also a stay informed advisory for O'Reilly and Cainbable, which is part of the Sarabah fire.

On the Sunshine Coast, a fire at Peregian — near Woodland Drive, west of Cormorant Crescent — has a stay informed advisory as well.

However, Acting Deputy Commissioner John Bolger encouraged residents to stay alert, as winds picked up over the next few days.

"They're westerly dry winds, predominately right across the state, so we'll have an increase in fire activity — nowhere near as bad as last weekend, but certainly we may reach the very high, may just touch into severe," he said.

Earlier today, QFES warned Sarabah residents to "prepare to leave" as the bushfire reared up again.

The mercury hit 30 degrees Celsius and an unfavourable wind change was fanning the blaze, which broke out last week.

"To be here today and see some of the incredible spirit of the response of those directly affected who've lost their homes through to those who are standing in canteens, standing in response groups, organising accommodation and logistics, it really is a tremendously impressive operation," Mr Morrison said.

"These natural disasters always have the most terrible of impacts but they bring out the best of Australians."

Mr Morrison said fire victims who had lost their income would be able to apply to the Department of Human Services for short-term support payments from next Monday.

"It supports people who are suffering income loss as a result of the economic impact of this disaster and of these fires."

Premier Annastacia Palaszczuk also visited the area this morning, thanking interstate firefighters who have been relieving local staff.

"This is what we do, people help, they come in from all different states and they pitch in and they help our community and we would do exactly the same for them," she said.
